With all the climate change attention I am hoping to find a CO$_2$ reference that can help me find a $\text{CO}_2$ reaction with $\Delta \text{S}^{\circ}$ less than zero, and ideally $\Delta \text{G}^{\circ}$ also less than zero, but heating is OK. The sought-after reaction is either spontaneous or can be made so, and endothermic. I would imagine such a reaction would be highly sought and so hopefully good reference data has been published.

  • $\begingroup$ What would you use those data for? Also, $\Delta \text{G}^{\circ}<0$ is the case of most ('spontaneous') reactions. $\endgroup$

  • $\begingroup$ By 'reaction' do you mean chemical reaction? $\endgroup$

  • $\begingroup$ I do mean chemical reaction. $\endgroup$

  • $\begingroup$ CO2 really isn't reactive at all. $\endgroup$
